Effect of Space between plants and Nitrogen fertilizer on Growth and Grain yield of Corn

Abstract

A field trial was conducted at farm of Qaim region silty caly soil to study the effect of space between plants and nitrogen fertilizer on growth and yield in Qaim .The objective of research is to determine the response of corn ( Booheth 106 ) in autumn season of 2005 fertilizer using three levels (80, 160, and 240) kg N/ha and using three spacing between hills (15, 25, and 35) cm, as sup plot. These factors( 3*3 ) were input in split plot design with three replication, seeds were planted at 20 july in rows 0.70 m spacing between. Nitrogen application incrased leaf area. Plant height and yield signifcantaly. So that 25 cm between hills gave the best means of these characteristics and resulted height rate of yield with using 160 and 240 kg N/ha.
